12.8.3.1 Interrupt Set-enable Registers
Name:
NVIC_ISERx [x=0..7]
Access: Read-write
Reset: 0x000000000
These registers enable interrupts and show which interrupts are enabled.
• SETENA: Interrupt Set-enable
Write:
0: No effect.
1: Enables the interrupt.
Read:
0: Interrupt disabled.
1: Interrupt enabled.
Notes: 1. If a pending interrupt is enabled, the NVIC activates the interrupt based on its priority. 
2. If an interrupt is not enabled, asserting its interrupt signal changes the interrupt state to pending, the NVIC never acti-
vates the interrupt, regardless of its priority.
